'"he i vention is for an improved weftpile velvet, and the same may beformed with cut pile of either cotton, or artificial silk for example.

The object of the invention is to produce or provide a fabric of thisnature which, in the finished condition, is apparently free from thetwill or parallel-line effect common to weft-pile velvets of ordinarykind. As is understood, this parallebline effect in an oblique directionacross the face of the cloth is sometimes rendered less apparent whenthe weft-pile velvet concerned is of the figured or pattern type, but inthose cases where the fabric is to be free from pattern, the said effectis commercially and artistically undesirable.

according to my invention, a plain or non-pattern fast bound fabric maybe produced which is apparently of a twill-less character on the faceside thereof, and thus has an appearance approaching that of a warp-pilevelvet cut in the loom.

In carrying out the invention, I so weave the cloth that the twill isrepeatedly reversed in direction down the length of said cloth, at theface tnereat, comparatively short lengths of said reversals beingsit-uated between ground picks of weft. Under the conditions nameo, thefinished velvet appears to be ree from the known parallel line effectreferred to at the face of the fabric, or is in a condition which hasbeen termed twill-less herein.

In the accompanying drawing, there is shown a form of draft forproducing the fabric according to my invention.

A repeat of the same is also included, the division between the twobeing indicated by a thick line in a vertical direction, and marked A.B.

The small circles indicate warp ends passing over pile picks of weft,and the crosses at the ground picks indicate where the warp ends passover ground picks of weft. Floats of weft between the ground picks areleft plain.

The ground picks are shown combined with warps in plain or tabby weave,as is understood, by way of example, the parts marked with crosses forone line of ground picks being arrangedalternately in relation to thenext and nearest lines of said picks. Some of the ground picks areindicated at l, and some of the pile picks at 2. It will be seen thatthe latter here float over seven ends of warp in each case. These floatsare afterwards cut in the hand cuttin frame, or, may be, in a powercutting machine, the

directions of cuts by the knife being indicated by arrow lines marked 3below the draft. The repeatedly reversing directions of twill formedaccording to my invention are indicated by the alternatingdirectionlines shown at 4, and merely introduced for explanatoryreasons, which pass between pairs of warp ends passing over picks ofweft marked at 5. These pairs of warp ends where so passing over picksof weft are seen to occur at alternate picks, and in a diag onal manner,the direction of the diagonal changing or reversing as indicated.

If the warp ends which are passing over successive. pile picks beconsidered instead of those over alternate picks, it might seem thatthey form a twill in a contrary direction, but in practice when thepicks of weft are squeezed together in the process of being beaten-up inthe loom, a parallel-line effect in said contrary direction is notapparent or said parallel-line effect at the face of the fabric isdue towarp ends passing over alternate picks of weft, and not over consecutivepicks before named, and understood in the weaving industry.

The pairs or groups of warp-ends forming twill referred to operate tomake the fabric of a fast-bound nature In the example there are ten endsof warp before the repeat, and sixty-four picks to the round, but thedraft given is an example of how groups of warpends passing over pilepicks of weft can be arranged in alternating manner, whether the draftbe strictly adhered to, or not, so far as length of floats and number ofpicks between pile picks are concerned. The warp-ends passing over pilepicks of weft are seen to be non-adjacent, or a warp end passes under apick of weft between a pair of warp ends passing over pile picksaforesaid in the case illustrated. In addition, as already named, eachpair or group of warp ends so passing over alternate pile picks isseparated from another pair or group thereof by at least one pick ofweft; that is to say, the warp ends which give the twill effects sopassing over pile picks at non-consecutive pile picks.

In the drawing the circles 5 and lines 4 indicate the changing manner inwhich the twill weave produced by the warp ends binding in the weft atthe face of the fabric occur according to my invention. If the twillweave were in one direction only down the piece of cloth, theparallel-line effect herein named would result as Well known, but whenthe direction of the twill weave as shown by the varying directionallines 4, takes a Zigzag course down the face of the fabric, and thenumber of picks of weft between the binding picks is not great, I findthat in the finished cloth so woven the parallel line effect is notapparent in either direction. The number of pile picks between bindingpicks in the illustration is suitable for obtaining the result named,although slight variations thereof will not affect the result desired toany practical extent.

I claim:

1. A fast-bound weft-pile velvet comprising floats of weft, bound in atextremes thereof by alternate warp ends passing over the weft at theface of the fabric, said alternate warp ends occurring at alternatepicks of said weft, after the manner of a twill weave, then a group ofbinding picks, followed by further floats of weft, bound in at extremesthereof by alternate warp ends passing over the weft at the face of thefabric, said alternate warp ends occuring at alternate picks of saidweft, after the mannor of a twill weave, the direction of said twillweave being opposite to that of the former twill weave named,repetitions of all the foregoing down the length of the piece, wherebythe directions of the twill weaves referred to take a zigzag course downsaid fabric, and whereby a twill-less velvet is produced after thecutting of the floats of weft and the finishing of the cloth, as hereinset forth.

2. A fast bound weft pile velvet comprising floats of weft, bound in atextremes thereof by pairs of alternate warp ends passing over the weftat the face of the fabric, said pairs of alternate warp ends occuring atalternate picks of said weft, after the man-- 11 0f a. twill weave, thena group of binding picks, followed by further floats of weft bound in atextremes thereof by pairs of aiternate warp ends passing over the weftat the face of the fabric, said pairs of alternate warp ends occuring atalternate picks of said weft, after the manenr of a twill weave,
